Police are asking motorists to stay vigilant after a fake police car, complete with flashing blue lights, tried to pull a driver over.

The motorist was travelling down a quiet Staffordshire road when he was tailgated by a car indicating he pull over.

Fortunately, the motorist had his wits about him and checked with police if the car was legitimate.

They confirmed it wasn't and are now trying to track it down.

StokeonTrentLive reports that the driver first noticed the suspicious vehicle as he made his way towards Weston at around 7pm on Valentine's Day (February 14).

A Staffordshire Police spokesman said: "We received reports of a suspicious car from a driver in the area of Weston Road and Hopton Lane, Stafford, at around 7pm on February 14. We are investigating the incident."

A relative of the driver took to social media to warn other motorists about the incident.

In her post, she said: "Just to make people aware, an 'unmarked' police car was tailgating my husband from the Knot and Plough pub towards Weston.

"He said it didn't seem right, there were not enough lights and they were right up his a*se. The car was black or dark with flashing blue lights just on the headlights.

"He carried on driving so to pull up somewhere busier and the car pulled off up Within Lane towards Hopton.

"We have rang the police and they have said it was definitely not an unmarked police car as currently they are elsewhere.

"Be vigilant. I'm not sure what the people in the car wanted but very glad my husband didn't pull over."

The official advice for anyone with concerns over whether a police car is genuine is to not stop in a secluded area and to instead drive to either a police or petrol station.

A police spokesman added: “We would like to advise the public that if you are not certain that you are being pulled over by the police, then do not stop in a secluded location.

“You should signal to show that you have seen the vehicle, and then make your way to a public place such as a petrol station or a police station.

“You can keep your doors locked until you are sure that it is a genuine police officer, and you can ask to see a warrant card which will carry their name and photograph."
